MILTON E. ST. JOHN, IVAN SEAL, AND LINLEY J. WINTEROWD, OF OELWEIN, IOWA.

HYDROCARBON-BURNER.

Application led August 5, 1915.

To all whom t may concern:

13e it known that we, MILTON E. ST. JOHN, lvAn' Sinn, and LINLPLY J. l.Vin'rnPowD, citizens of the United States, all residents of (lelwein, in the county of Fayette and State of iowa, have made a certain new and useful invention in flydrocarbiui-Burnersg and we declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which forni a part of this specification.

Figure 1 is a side view of the invention as applied. Fig. 2 is a section on the line 2 2, Fig. 1. Fig. 3 is a plan view of the invention.

The invention has relation to wiekless hydrocarbon burners, designed mainly for use with kerosene, and it consists in the nevel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 2 designates the pressed steel body or frame, 3 an oil reservoir mounted upon said body, 4 a shelf or transverse support, 5 a main or central burner, having a standard G adj ustably engaging a sleeve 7, mounted upon said shelf, and iiXed in its adjustment by a set-screw 8. The burner 5 has a hollow base casting 9, provided with lateral tubular arms 10, 10 leading to lateral burners 11, 11, mounted at the ends of said arms, said lateral burners having turnbuekle connections 12, 12 with said shelf, to render the three burners perfectly level.

The base casting t) of the central or main burner has a plurality of upward extending tubular branches 14, 14, usually four, as shown, each couple of branches having at their upper ends communication with a hollow casting 15, usually of straight cylindri- :al form and provided with suitable perforations or slits 16, and forming the burner proper, the two castings 15, 15 being parallel and spaced apart from each other.

Located in the space between, and parallel to the burners 15, 15 is the generator tube 17, having therein a brass rod or core 17', concentric therewith and of diameter smaller than the tube, a hollow nut 18 being provided at the end of said tube, within a perfor:-

tion of which the outer end of the core fits, said nut being illed with suitable packing material.

19 designates a generator head casting, of angular form, having therein an angular passage 20, with the inner end of which the pointed inner end 21 of the brass generator core has loose engagement, the vaporized fuel passing around said pointed end of the core into said passage in thin sheet form. a pointed valve rod 22 having engagement with a lateral discharge opening 28 at the lower end of said passage, to control the exit of the fuel vapor. A screw closes the lower end of the passage.

25 is a vertical air intake tube, the generator head casting being located at the upper portion of one side of and over said tube.

2G is a horizontal air-mixing tube, open at both ends and located within the main burner casting, with a perforation .27 of one side of which it has engagement, said mixing tube being in line with the fuel discharge opening 23 of the generator head casting.

Oil, under pressure, is fed to the generator tube by a line copper tube Q8, air pressure being supplied to the reservoir from a suitable source, as a hand pump Q8. The oil reservoir has usually a filling tube Q9, provided with a cap 30, and is supplied with a suitable pressure gage 31, and a valve 32 to close the air supply.

In operation, the air intake tube and generator head casting have heat applied thereto by a suitable torch,when` the valve Q2 being operated to open the fuel exit, the vaporized fuel will be discharged under pressure into the air mixing tube. drawing up air through the air-intake tube, such air passing with the fuel into the mixing tube. The admiXture of vaporized fuel and air from the main burner casting passes upwardly .into the burners proper, where it is ignited.

The generator tube being located between and close to the burner tubes and to the flame, will be constantly heated in an even manner, te facilitate vaporization of the fuel, which passes in annular thin sheet form around the core rod of the generator tube to the passage of the head casting.

The valve controlling the operation of the stove being located at the extreme end of the fuel passage is designed to eliminate all odor of gases when shut ott. The fuel tank Patented Mar. 21, 1916. t

is located directly under the burners and admits of the use of larger tank than in any other location.

The branch tubes supplying the end or latv;l eral burners are provided with suitable controlling valves l0.

The tubular branches ll, M are not regarded as essential, as the hollow casting l5 may be provided with a circular opening at i bottom. taking the 'Y lace of these branches.

le claim:

In a hydrocarbon burner, a hollow main casting, a burner tube overlying and having communication with the interior of said casting, a generator tube close to said burner line with said air mixing tube, a valve controlling said discharge opening, laterally eX- tending branch tubes from said main casting, lateral burners in communication with said branch tubes, valves controlling said branch tubes, a support for said main casting including a vertically adjustable standard provided with a set screw to fix the adjustment, and leveling turn buckles in connection with said lateral burners.

In testimony whereof we aiiix our signa tures in presence of two Witnesses.
